Feedback amp debuts

Norwood,Mass.- A high-speed, current feedback amplifier from Analog Devices Inc., the AD8007, lets designers minimize supply voltage circuitry or battery requirements and reduce cooling requirements. As a result, the device can help companies lower costs, build higher-density boards and increase system reliability.

The amp offers 600 MHz of bandwidth (G = 1), a slew rate of 1,000 volts/microsecond, second harmonic distortion of -88 dB at 5 MHz and -80 dB at 20 MHz, and third harmonic distortion of -101 dB at 5 MHz and -84 dB at 20 MHz.

It is available in an SC70 or an eight-lead small-outline IC, rated over the -40 degrees C to +85 degrees C industrial range and is priced at $1.19 in 1,000-piece lots. The unit is in production. Samples of a dual version, the AD8008, are expected soon, the company said.
